raised and can be adjusted to the desired pitch.
The Ibanez DOWNSHIFTER allows the pitch of a string to be dropped to a preset
desired position with a simple lever operation. To achieve precise tuning for both the
up and down positions, you will need to preset both lever settings before operating
the Downshifter.
TUNING
First check that the Downshifter lever arm is raised to the up position then tune the
string normally using the standard tuning machines on the headstock.
(Note: the Downshifter tuning screw has no effect on the pitch in the up position.)
Next, lower the lever on the Downshifter to the down position and the pitch of the
string will drop down. Adjust the rear tuning screw clockwise to reduce the pitch, or
counter clockwise to raise the pitch. This adjustment can be done by hand or with a
standard screwdriver or a coin until the desired down pitch is acquired. (The preset
factory pitch is set one whole step down to D.) When the lever is raised to the up
position, the thumbscrew can be turned freely but will have no effect on the raised
lever pitch. However, it will affect the settings of down lever pitch.
PLEASE NOTE: The Downshifter device was designed to provide the highest level of pitch accuracy. However, it
should be understood that the Downshifter is a mechanical device. Pitch variations and tuning readjustments,
especially after frequent use, are to be expected.
TIGHT-TUNE BRIDGE
The Tight-Tune bridge achieves the optimum in stability and sound transference while suppressing unnecessary
vibrations by allowing each part of the bridge to be locked.
STRING HEIGHT ADJUSTMENT *
String height can be adjusted by loosening the lock nut (A) on both sides of
the bridge and turning the stud bolt (B) with a 3mm hexagonal wrench (E).
After adjusting the string height, tighten the lock nut (A).
NOTE: * Always be sure to unlock the interior stud lock screw before adjusting the string
height. Otherwise, damage may occur.
STUD LOCK FUNCTION
The Tight-Tune Bridge has a stud lock function. This fixes the stud bolt (B) to
the guitar body securely after finishing string height adjustment.
Before performing string height adjustment, completely loosen the stud lock
screw located on the interior of the bridge stud (F) in a counter-clockwise
direction using a 2mm hexagonal wrench (H). After finishing the string
height adjustment, turn the interior stud lock screw clockwise (F). When the
screw touches the anchor nut (G) and cannot be turned further, it is locked.
INTONATION ADJUSTMENT
To adjust the location of the saddle, loosen the saddle lock bolt (C) on the
saddle to be adjusted and turn the intonation adjustment screw (D). Tighten
the saddle lock bolts again (C) after finishing adjustment.
*Hint: Resonance may occur if the intonation adjustment screw (D) is loose. In this case,
lightly tighten the intonation adjusting screw (D) until the saddle does not move.
REPLACING THE STRINGS
The Tight-Tune tailpiece is equipped with a ball-end lock function, which
doesn't allow the ball-end to separate from the tailpiece when replacing the
strings. When installing the string, insert the ball-end into the slot of the
tailpiece as shown in Fig. 1. The string can be removed easily by pulling it in
the direction as shown in Fig. 2.
